Research Highlights

We clarify the terminology surrounding yield gaps, show that closing yield gaps is not necessarily economic, and conclude that food security will be better served by policies that directly enhance the productive capacity of agriculture to supply affordable food efficiently and sustainably.

This technical note describes the methods and data sources used to generate the results reported in: Pardey et al. (2013).

The notion that global agricultural output needs to double by 2050 is oft repeated.

Authors use crop and impact models to examine which current and potential agricultural technologies offer solutions to fight hunger.

HarvestChoice Web Map services

HarvestChoice Web Map Services (version 1.1.1) offer Open GIS Consortium standard Web Map Service interface. Using WMS endpoints, you can allow your desktop or web GIS clients (e.g. QGIS and ArcMap, Leaflet, etc.) to access all of HarvestChoice data layers for sub-Saharan Africa without this website.

Cover Atlas of African Ag

The Atlas of African Agriculture Research & Development presents a broad range of geospatial data that relate to strategic agriculture policy, investment, and planning issues.

Soil organic carbon content (fine earth fraction) at 15-30cm depth.

Our new spatial output indexes show that 16 to 21 percent of the increase in U.S. corn output over the 128 years beginning in 1879 was attributable to spatial movement in production.

Model-estimated yield variability of rainfed maize with high input for 1981-2010 (30-year period). Values are for 5 arc-minute grid cells.

This tool helps users to identify specific sites within the SAGCOT (Southern Agricultural Growth Corridor of Tanzania) area where new irrigation investments should target at 10 km spatial resolution.
